DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a natural lithographic formwork block having natural stone layered on its surface.

[0002]

2. Description of the Related Art In a conventional masonry structure of a concrete block wall, a concrete block to be masonry is provided with a retaining portion, and concrete is poured between the blocks to be integrated.

[0003]

In the conventional masonry structure of the concrete block wall, since the surface is composed of the concrete portion, the surrounding of the surrounding area is contradictory to the existence of the artificial joint joint of the concrete block. The harmony with the natural environment was spoiled, and the integration of each block was difficult.

The present invention has been made in view of the above problems, and has as its object a natural lithographic mold that is in harmony with the surrounding natural environment, has excellent workability, and is structurally highly reliable. It is to provide a construction method of a frame block.

[0005]

In order to achieve the above object, a method for constructing a natural lithographic formwork block according to the present invention is to form a pedestal by stretching a wire netting on a steel angle material, and forming the pedestal on the pedestal. Natural stones were lined up and bonded to the wire mesh via an adhesive, and the integrated steel angle material, wire mesh and natural stone were dropped into a formwork previously poured with concrete, and the concrete was hardened. The mold was then removed from the mold to produce a natural lithographic formwork block with natural stone integrated into the surface. After installation and fixing, the natural lithographic formwork block is used as the lowermost natural lithographic formwork block, then the upper fixing bracket is attached to the back of the natural lithographic formwork block via the insert bolt, and then the lowermost natural formwork Natural stone A cast-in-place concrete is poured between the form block and the backing material up to the first casting surface, and then a second-stage natural lithographic form block manufactured in the same manner as above is lifted to form the lowermost natural lithographic block. It is installed at a predetermined position on the upper surface of the formwork block and is connected to the upper fixing metal fitting. Then, the upper fixing metal fitting is attached to the upper rear part of the second natural lithographic formwork block, and the second natural lithographic metal plate is used. The present invention is characterized in that cast-in-place concrete is placed between the formwork block and the backing material up to the second placement surface, and the same steps as described above are repeated to form a slope-covered concrete wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a method for constructing a natural lithographic formwork block according to the present invention will be described with reference to the most preferred embodiment shown in the drawings. A wire mesh 2 is stretched on a frame made of a steel angle material 1 to form a pedestal, and natural stones 3 are arranged on the pedestal and bonded with an adhesive 4 such as an epoxy resin to form a pedestal. The stone 3 is integrated (see FIG. 1 (a)), and the integrated wire mesh 2 and natural stone 3 are dropped into a formwork 6 previously filled with concrete 5 (see FIG. 1 (b)). After the concrete 5 has hardened, the mold 6 is removed from the mold to produce a natural lithographic mold block 7 integrated with the natural stone 3 (FIG. 1).
(C) and (d)). Next, a method of applying the natural lithographic formwork block will be described.

A foundation 8 is constructed by casting concrete (see FIG. 2), and the natural lithographic formwork block 7 manufactured as described above is fixed to the foundation via a fixture 9 of a foundation attached to the back surface thereof. 8 and fixed at a predetermined position and slope to make the natural lithographic form block 7 the lowermost natural lithographic form block (see FIG. 3). The fixing bracket 9 has a lower L-shaped vertical piece fixed to the natural lithographic formwork block 7 via an insert bolt, and an inclined piece extending obliquely upward from a horizontal piece tip of the L-shaped piece. Is fixed to the back of the natural lithographic formwork block 7 via an insert bolt.

After fixing the lowermost natural lithographic form block 7 to the foundation work 8 via the fixing metal 9, the upper fixing metal 9 'is attached to the back of the natural lithographic form block 7 via an insert bolt. Installation, cast-in-place concrete 11 between the natural lithographic formwork block 7 at the bottom and the crushed stone 10
Is installed to the _first installation surface S1 (see FIG. 3). Next, the second-stage natural lithographic formwork block 7 'manufactured in the same manner as above is lifted, installed at a predetermined position on the upper surface of the lowermost natural lithographic formwork block 7, and connected to the upper fixing bracket 9'. .

[0008] Then attach the '' top of the fixing bracket 9 to the upper rear of 'the second-stage nature lithographic mold blocks 7 and pouring the scene strokes concrete 11 until the second punch設面S ₂ (FIG. 4 reference). Thereafter, the same steps as described above are repeated to form a slope-covered concrete wall, and finally a natural lithographic formwork block is disposed at the top (see FIG. 6). Reference numeral 12 in FIG. 5 is a drain hole.

[0009]

As described above, the method for constructing a natural lithographic formwork block according to the present invention forms a pedestal by stretching a wire mesh on a steel angle material as described above, laying natural stones on the pedestal, and attaching the wire to the wire mesh. The steel angle material, wire mesh and natural stone are integrated and dropped into a formwork in which concrete has been poured beforehand. The integrated natural lithographic formwork block is manufactured, and the natural lithographic formwork block is fixed to a foundation work at a predetermined position and at a predetermined gradient via a fixing bracket of a foundation attached to the back, and the natural lithographic formwork block is manufactured. The block is the lowermost natural lithographic formwork block, then the upper mounting bracket is attached to the back of the lowermost natural lithographic formwork block via an insert bolt, and then the lowermost natural lithographic formwork block and backing material Between Casting concrete to the first casting surface, then lifting the second-stage natural lithographic form block manufactured in the same manner as above and placing it at a predetermined position on the top surface of the lowermost natural lithographic form block; It is connected to the upper fixing bracket, and then the upper fixing bracket is attached to the upper part of the back of the second-stage natural lithographic formwork block. Punched concrete is poured up to the second casting surface, and the same steps as above are repeated to form a slope-covered concrete wall. And can be harmonized with the surrounding natural environment.

[0010] As described above, the natural lithographic formwork blocks are vertically stacked in multiple stages along the slope, and the cast-in-place concrete is cast between the natural lithographic formwork blocks and the backing material in each step. Therefore, joints between the natural lithographic formwork blocks can be eliminated.

Further, as described above, the natural lithographic formwork blocks are piled up and down in multiple stages along the slope, and cast-in-place concrete is cast between the natural lithographic formwork blocks and the backing material in each step. Therefore, it can correspond to the slope of every slope.

Further, as described above, while the natural lithographic formwork blocks are laid up and down in multiple stages along the slope, the cast-in-place concrete is cast between the natural lithographic formwork blocks and the backing material in each step. The construction is easy and the construction cost can be reduced.
